[Zope] external editor and pythonwin

[Sune Brøndum Wøller]

Hi,
I have a problem with external editor and editing python scripts 
with pythonwin.
It works fine if pythonwin is not open when I
edit a script by clicking on the pencil.
But if pythonwin is already open, I get the
error:
"external editor lost connection to editor process"
The script is loaded in pythonwin, but the connection to Zope is lost.

anyone have a solution ?
